Note: Before you create and use metaslots (slot metaclasses), you should be confident with the basic Protégé interface and be comfortable designing a project, and creating and modifying classes, slots, forms and instances.
If you have multiple metaslots in your project, Protégé allows you to
choose which metaslot you want to use as the default for every new slot you
create. The default metaslot is denoted by a Default
icon at the right.
To set a metaslot as the default:
It is also possible to remove the default property from a metaslot without designating a new metaslot. To do this:
If you do this, no default metaslot will be designated. In this case, if you have only one concrete metaslot, it will be used as the default. If you have more than one concrete metaslot, then you will be prompted to choose a metaslot each time you create a new slot.
